SPECFlCATON forming part of Letters Patent No. 710,778, dated October 7, 1902.

Application tiled January 6, 1902. Serial No. 88,540. (No modell) To (all wh/mt '/l muy concern:

Be it known .that I, JAMES HoRsLur, a citizen of thc United States, residing at Glade Mills, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Oil-Well Pumps, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of this specification, in which- Figure 1 is a partial sectional view of my improved pump inserted in the tubing of a well, the liner-valve barrel being shown in its lowermost position. Fig. 2 is asimilar view showing the liner-valve barrel raised to the limit of its upward stroke.

showing the liner-valve barrel lowered, corresponding to Fig. 1. Fig. is a similar view showing the liner-valve barrel raised, corresponding to Fig. 2, the liner-valve or stand.

pipe in both Figs. 3 and a being shown in elevation. Fig. 5 is a vertical sectional view, on a further enlarged scale, of the upper portions of the liner-valve or stand-pipe, illustrating the construction and arrangement of' the packing, packing-rings, and other details, the surrounding liner-valve barrel being also shown in section. Fig. o' is a View in elevation of the upper sections of the linervalve barrel, the packing-rings and a portion of the upper packing` having been removed. Fig. 7 is a detail perspective view, partiallyin section, of the upper spring-bearing ring. Fig. S is a similar view of one of the interfitting split packing-rings. Fig. 9 is a similar view of the lower fluid-compression ring. further enlarged scale, showing the lower end of the liner-valve, the liner-valve barrel, andv Fig. 23 is a partial sectional view, on an enlarged scale,

Fig. .10 is a sectional view, on a-l Fig. 12 is a cross-sectionai oil-well or other Huid pumps, and has for ils object the construction of a pump adapted to be located in the tubing and working barrel of the well and to elevate the fluid therethrough by reciprocating movement of a linervalve barrel with the various. details of construction aud mode of operation as shall be more fully hereinafter set forth.

'wardly therefrom a short section 9, terminating in a removable cap 10, preferably secured upon the lower end of the section 9. The cap 10 is provided with a number of perforations 11, through which the oil freely passes upwardly into the interior of theliner-valve upon upward motion of the liner-valve barrel. The section 9 is provided with a plurality of packing-rings 12, tightly engaging around itin position and adapted to t against the interior of the Working barrel 3 and to make therein a fluid-tight t and to bear with sufficient force to support the liner-barrelin position preferably immediately above the standing valve 4. l

The liner-barrel A is provided at its upper end with a standing valve 13, the case of which is screwed upon the top of the upper section 7, as shown, adapted to {permit upward travel of iiuid and to prevent its return downwardly. Ther sections 6 and 7 are preferably tapered, as clearly shown in Figs. 5

Vand 6, so that as these sections are brought 'and repack these parts.

Surrounding the stationary liner-barrel or stand-pipe is the liner-valve barrel,consisting of a tube or shell 14C, adapted to reciprocate IOO up and down, and between such barrel and the sections G and 7 is interposed the packing just referred to. The section 7 is wrapped with any suitable packing substance-as, for instance, wool (indicated at 15) or any other suitable ordesirable materialan adjustable thimble 16 being preferably provided immediately underneath the standing valve 13 by which such packing may be compressed, and for the purpose of providing a seat therein the thimble 16 is undercut on a bevel, asindicated at 17. The section 6 is surrounded by a series lof split rings 1S, (shown in detail in Fig. 8,) the split therein being preferably at an angle, and each of such sections is tapered upon the outside upper portion, as Shown at 19, and at the. lower inner portion, as shown at 20, so that a when a series of such rings are assembled around the section of pipe they will nest into each other and each ring will tend to expand the next adjacent one under longitudinal pressure. The lower packing-ring 21 is preferably solid and rests upon the coupling 8,while the uppermost ring 22 (shown in detail in Fig. 7) is also preferably made solid and is hollowed out in the interior, as at 23, for the purpose of receiving packing material 24. As thus assembled the series of split rings,\vith the terminal solid rings, provides a means for packing the interior of the liner-valve barrel by the exertion thereon of longitudinal pressure. Such pressure is exerted by a stid coiled spring 25, surrounding the upper end of the section 6 and bearing against the coupling 8 and ring 22. The lower end of the barrel 14 is provided with an annular terminal extension 26, surrounding the section 5, and provided with a series of inner longitudinal ports or passages 27, by which upon downward movement of the barrel oil may pass upwardly around the outside of the section 5 and to the interior of a bell-shaped ring 2S, (shown more clearly in detail in Fig. 9,) the purpose of which is to permit a limited amount of oil to pass upwardly between it and the section 5 in the space 29 on the downward stroke of the barrel, but which will retard the flow of the oil in the upward stroke of the barrel, and will thus provide through such intervening oil in space 29 and in the space above between section 5 and the linervalve barrel 14 back pressure against the packing-rings 18, so as to approximately equalize and counteract the pressure upon them from above. Thus in the downstroke by reason of the inner tapering face 30 of the ring 28 fluid will pass upwardly into the space 29, from which, however, it will not so readily escape in the upward travel of the barrel, but will be compressed therein, thereby thus accomplishing the desired end of providing a counteracting pressure below.

The barrel is provided at its upper portion with a cage 31, carrying a check-valve 32, adapted to open on the downward stroke1 permitting oil to flow outwardly from the interior of the barrel to the interior of the tubing 2, the Valve seating itself upon the upward stroke and the volume of oil above the valve being raised during such upward stroke by a connecting or sucker rod or pitman 33, secured, as shown in Fig. 3, to the upper portion of the cage. As thus constructed when the liner-valve barrel has been lowered in the working barrel (the entire structure, including the outer barrel, being lowered by means of the connecting-rod 33) reciprocating motion of the liner-valve barrel 14 will on the upward stroke create a suction in the interior of the liner-barrel A, causing fiuid to pass upwardly through the standing valve 4 into the interior of the sections 9, 5, 6, and 7, raising valve 13 and filling the space within the linervalve barrel above such Valve 13 and below the Valve 32. Upon the downstroke Valves 13 and standing valve i will be seated, valve 32 will open and oil will ow outwardly above such valve to the interior of the tubing and be raised therein and discharged therefrom in proportionate quantities at the top of the well upon each subsequent operation of the pump. The construction as I have shown and described it is very eflicient in operation, the packing is capable of performing its functions in a highlysatisfactory manner, provision has been made at all points for taking up wear, and the pump has in continuous practice proved to be an efficient device for the purpose.
